Description
Technical field
This utility model relates to a kind of movable machinery equipment fault on-line checking diagnostic techniques, particularly relates to based on urban track traffic
The vehicle-mounted distributed fault diagnostic system of train EEF bogie fault.
Background technology
Track traffic industry unconventional ground, domestic city high speed development, several big data fully indicate this situation: by 2014
At the year end, existing 22 cities, inland of China build up and put into effect rail line 101, and it is public that operation mileage breaks through 3000
In；2014 domestic newly increases Changsha, Ningbo, the urban track traffic of three, Wuxi put into effect, newly-increased 9 city rail traffics fortune
Battalion's circuit, newly-increased operation mileage 409 kilometers；2014, the track traffic in about 3300 kilometers of city, 36, inland of China was being built
Project, completes to invest 285,700,000,000 yuan altogether, say, that within 2014, China puts into subway construction fund daily more than 7.8 hundred million；
By the end of the year 2014, domestic existing 38 cities of state approval are through building track traffic, and planning total kilometrage is close to 7000 kilometers；
Beijing, Shanghai, a few big city, Guangzhou metro operation mileage are the most already more than 200 kilometers, and particularly Shanghai rail transit scale is
Become the first in the world.
Being continuously increased of operation mileage, the input successively of large number of rail traffic vehicles, the big or middle isotactic in more than 20, the whole nation
Mould city, rail traffic vehicles just runs in urban population compact district, these vehicles are all more than ten hour every days, 2 minutes very
To shorter operation interval time, at full capacity, even run quickly on the run in orbit to over loading.
Face the scale that track traffic industry operation in domestic city has had, and also in the office of lasting unconventional ground high speed development
Face, a problem is the most gravely confronted: how to guarantee the safety that urban railway transit train is runed.Various places subway line
Constantly extend, the accelerated ageing under being continuously increased of vehicle fleet size, and equipment over loading operation so that in recent years, vehicle trouble
Incidence rate is in the trend risen, and its fault severity level also has the symptom of a trend of constantly rising.Metro operation and relevant departments are over the ground
The attention of ferrum car operation safety problem is nearly at close to extreme degree, works with all tightening one's nerve every day, to each possible
Risk link all makes every effort to make can be perfectly safe, to guarantee safe prediction scheme.
In preventing various vehicle troubles, prevention EEF bogie safety failure is its most important thing.Whole load of rail vehicle all add
Being loaded on EEF bogie, travelled by vehicle portion once breaks down, the most then face and stop the proteges of the powerful who stay with their benefactions like parasites, heavy then cause the serious person, equipment, road
Accident.
Rail vehicle EEF bogie failure problems, except bringing pressure to daily operation, there is also that workload is big, safeguard in many lances
The problem that shield interweaves: the train of conventional system goes back to storehouse and checks have hysteresis quality；EEF bogie critical component such as bearing gear wheel
Tread quality state, particularly bearing, be tracked by the method for patch thermometric reagent paper, it is impossible to reality when reflection runs completely
Situation；The virtual condition of different service condition lower bearings is different, and maintenance requirements is the most different；EEF bogie axle box bearing gearbox shaft
The maintenance cycle held and the wheel cycle of changing of wheel do not mate, and cause needing that train repeats button and stop maintenance, and some parts is not
Dismounting it is accomplished by, when changing box bearing such as electric rotating machine vehicle, it is necessary to dismounting wheel and axle box axle during to maintenance cycle
Holding, these problems, not only cause the loss of excessively maintenance, also significantly increase maintenance cost, effect is the most undesirable.
The ability of safety monitoring and safety guarantee in order to improve locomotive running gear, in 2013, this utility model people applied for reality
With novel " a kind of railway locomotive EEF bogie On-line Fault monitoring diagnosis system " (ZL201320679842.5).This technical scheme
Use advanced " the mechanical fault diagnosis technology of generalized resonance and resonance and demodulation " in know-why, efficiently solve common
Railway, the early warning of part high ferro locomotive running gear fault, fault be accurately positioned and ground in the face of locomotive operation operating mode continuous with
Tracks etc. need.But, this system in common railway field successful Application, it is impossible to indiscriminately imitate urban track traffic system simply
System.City Rail Transit System has the operation characteristic being different from common railway.Such as, " a kind of railway locomotive EEF bogie
On-line Fault monitoring diagnosis system " (ZL201320679842.5) just for separate unit locomotive, it is impossible to and networking, this cannot adapt to
The railcar of many marshallings；Relative to common railway locomotive, rail traffic vehicles has its particularity run: fix according to permutation
Marshalling runs, and usually 6-8 railcar is organized as string, and from the point of view of EEF bogie structure, is divided into again 2 kinds of vehicles: one
Plant is that EEF bogie every axle is with driving motor, i.e. motor-car；Another kind is that every axle is without driving motor, i.e. trailer.Rail
The aspects such as road vehicular traffic permutation marshalling, travelled by vehicle portion structure, operating condition and application and maintenance management system, are all different from general
Logical railway.
The most such as, compared with the common railway locomotive run on territory vast in territory, the rail transportation operation state in each city,
It is in the fixing car group of relatively limited quantity, the most repeatedly runs on the fixing circuit of relatively limited distance every day.
The repetition unit of track traffic this feature reruned on the track repeated, results in the rail corrugation of urban rail circuit
Problem is the most prominent.Rail corrugation all can produce strong influence to wheel rail relation, train EEF bogie fault: rail corrugation changes
Normal rail wheeling action relation, the kinetics function being degrading between wheel track, make each parts between wheel of vehicle and Track rail
Duty deterioration, accelerate the mechanical damage of the relevant installing components such as bogie, the risk overstepped the limit when increasing train operation, and
Routine servicing maintenance cost；Ripple mill also affects the comfort level that passenger takes, and the howling sent when train is by ripple mill rail is
One of main source of rail transit noise, takes vibration reducing measure inoperative.And these problems, common railway locomotive is not dashed forward
Go out.
In January, 2015, this utility model people has applied for utility model " a kind of portable subway travelled by vehicle portion test diagnosis system "
(201520012082.1), this Technology application " the mechanical fault diagnosis technology of generalized resonance and resonance and demodulation " principle, symbol
Be fated modern equipment safeguard protection early warning in advance, the demand for development of Accurate Diagnosis, has again portable construction, the convenient feature used,
Can be used for suspicious metro vehicle traveling part position carrying out interim trial diagnosis, instructing railcar to run and maintenance.
But, this technical scheme is equipped with equipment design not as the standard of railcar, but as portable set, non-
Vehicular equipment designs, and uses liking for the existing vehicle of the subway not being equipped with onboard diagnostic system, can facilitate when needed,
Apply neatly.Just because of this, this technical scheme is in place of structurally and functionally also having certain limitation, reservation and shortage.
Such as, dismounting is needed after portable detection equipment has been tested；Diagnosis can not be given the most in real time, but need to examine
Survey after Ground analysis management software is downloaded and imported to data and just can provide diagnosis；Cannot function as the online equipment of vehicular to use.
At present, also there is also other system miscellaneous based on metro vehicle traveling part detection both at home and abroad, but the most only rest on and shake
In the level of dynamic parameter detecting or temperature detection, owing to not using " the plant equipment event of generalized resonance and resonance and demodulation of advanced person
Barrier diagnostic techniques ", do not possess fault diagnosis pre-alerting ability, especially to initial failures such as bearing, gear, tread, track ripple mills
